Running VMs Capped?

[Xenofish]

I'm in the middle of a project that requires 1800~ VMs , and seem to have encountered a cap in the amount of virtual machines I can launch on a single system. On a windows host system, (Windows Server 2008R2, 6 Core AMD, 16GB of memory) I've gotten 70~ of these VMs to run stable (TinyCore Linux 2.6, runs in 50MB of HDD space and 150~ MB of memory), but on a Linux host system (Ubuntu 10.10, 128 Core Intel Xenon, 2.0TB of Memory), I get a hard cap of 128 VMs. Did I miss some configuration item somewhere on the Linux host or is this a static cap?

AFAIK 128 is the limit.

Is that documented anywhere? If this is indeed a hard cap... I'm going to have to do something tricky or find another solution.

I know there was some discussion about it a while back and they did fix something in Solaris host that allowed more than 128 but you would need to ask the DEVs if this is so on Ubuntu.
Send email to them over the DEV mail list. http://www.virtualbox.org/wiki/Mailing_lists
